Railroad crossing safety device

ABSTRACT

This system is a special device known as the hybrid sound detector (HSD) composed of electronic components attached to two separate printed circuit boards mounted in a hand held plastic box that can be installed in any motor vehicle, train, car and airplanes near the operator. The first part of the HSD schematic board is a sound level meter that measure the sound level in noise range 110 to 114 decibel. The sound circuit board of the HSD schematic board is a driver circuit with low-level signal. A small red light and mini buzzer are visible and connected to the two electronic circuit boards.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The invention relates generally to various other means of preventingaccidents at railroad crossings.

#1-1

U.S. Pat. No. 6,116,546 issued Sep. 12, 2000 to Fort N. Burkhartdescribes a process for creating a flashing red light at arailroad-highway grade crossing. This process is revealed as a flashingred light that causes motorist and others to be aware that a train isapproaching the grade crossing. The light unit is located to the frontof the train 13 to 15 feet above the railroad tracks. A reflector unitis mounted at the crossing grade equal to the same height as the lightunit.

U.S. Pat. No. 6,195,020 issued Feb. 27, 2001 to Ronald E. Bradeur, Sr.,a system that can detect the presence of a vehicle within the area of afour-gate railroad crossing, determining its location and direction. Thesystem is equipped with a series of magnetometer sensors capable ofdetecting the presence of a vehicle entrapped inside an area of afour-gate railroad crossing. The exit gates are used to allow theentrapped vehicle to escape.

#1-3

U.S. Pat. No. 5,414,406 issued May 9, 1995 to Melburn J. Baxter, aConventional Horn composed of an electronic switching circuit thatoperates at a switching frequency equal to the reason frequency of thehorn. A transducer and signal conditioner produces a horn output pulsetrain at a frequency equal to the acoustic output of the horn. The sweepfrequency output oscillator is applied to the other input of the phase.The phase comparator generates a stop signal for the sweep frequencyoscillator when the input signals are in phase with each other andsignifies that the horn is operating at its reasonant frequency.

SUMMARY OF THE INVENTION

The railroad crossing safety device is an electronic box composed ofintegrated circuits that were designed to automatically measure soundlevels in a designated area. The box dimensions are 3″×6″×2″ in size.Standard fasteners are used for mount the box in a secure locationclosely or near the operator of any and all mobile equipment. Theconstruction of the box is made from metal on plastic materials with aninternal circuit board powered by the primary source of electricity andback-up of nickel plated batteries in case of power interruption.

BRIEF DESCRIPTION OF THE DRAWING

FIG. 1 is an electronic schematic compound of two independent sectionsthat are grouped together to set off warning signals comprised of lightand sound. Section AA and BB display electrical components that willrectify and carry warning signals to a red light and a small buzzer.

DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 is a device set up to save lives at all railroad crossings. Avery unique electrical sound will be activated in any car, bus, truck,motorcycle or any type of motor vehicle when two or more objects comewithin 5000 feet of each other. The hybrid sound detector (HSD) is anelectrical device made up of an integrated electrical device made up ofan integrated electronic system. The system if used to compensate forpoor visibility and lack of early sound detection. Deaf and visuallyimpaired individuals will benefit significantly from this specialdevice. However, in most collision accidents the operator sometimesdevelops an impairment known as attention disorder This occurs when aperson is not aware of his surroundings for a very short period of time.The system is a special device that will meet the safety needs ofpassengers and operators at railroad crossings, air routes, waterwaysand highways.

Section AA and BB of the hybrid sound detector's main function iscreated by using two different circuits. Each circuit is able tofunction alone. The device's dependability is identified as a cascadedcoupling. Section AA of FIG. 1, hybrid sound detector as designed servesas a sound level meter. Sound levels are measured as noise range 110 to114 decibels with sound level devices. FIG. 1 of Section AA and BBintegration activates fast mode to detect noise 110 to 114 decibelsselection range.

1. Is an electronic safety device constructed to notify operators of apossible head on collision with other motor vehicles in mid-air,waterways or highways. The device dimensions are 3″×6″×2″ and could bepowered by both secondary and primary power supply. The hybrid sounddetector FIG. 1 of section AA-BB main function is to measure sound levelhosed in a range of 500 feet.
 2. BB of FIG. 1, hybrid sound detectorelectronic schematic design driver circuit is driven by externallow-level signal. FIG. 1, Section AA and BB total output of drivercircuits activates #1 light and #2 mini buzzer with piezo thresholdbetween 110 to 114 decibels sound level. The total output of the drivercircuit activates #1 light and a mini buzzer #2 notifying the operatorvisually and by audio sound before a collision takes place.
 3. Thisdevice FIG. 1 combines Section AA and BB to activate safety devicecompensate for poor visibility and lack of early sound detection. Thedeaf and visually impaired individuals will benefit from the hybridsound detector. Claims:
 1. Railroad Crossing for automobiles
 2. Earlywarning for the deaf and visually impaired
 3. Prevent air collisions
